It was relatively easy for him to construct this Mental Space—or at least, that's how Aur felt. Perhaps his understanding of Time and Space Magic made the difficulty feel like it was set to "easy mode."
In just a few moments, using the gathered resources from Stella—which were not particularly rare—Aur had already reached the final step.
"Hmm."
Aur gazed at the giant furnace, which was gradually heating up. The dark green liquid was visible through the glass covering the front of the furnace.
Slowly, he extended his hand.
"Are we ready, Stella?"
"Yes, master." Stella nodded silently.
Whoosh!
The furnace lid opened, and the green liquid floated out as if defying gravity itself.
Aur then extended his hand, and the green liquid immediately became attracted to him like metal to a magnet.
Slowly, it covered his entire body in a domain-like structure.
He sat down cross-legged and closed his eyes.
